Q: What does territorial patent mean?

Territoriality of a patent means that a patent granted in a country or region is valid only in that country or region. The same invention can be patented in multiple countries or regions at the same time.

The five largest patent offices in the world are the State Intellectual Property Office of China (CNIPA), the European Patent Office (EPO), the Japan Licensing Office (IPO), the Korea Licensing Office (KIPO) and the United States Patent and Trademark Office (USPTO).
